The previous owners had been producing condensed milk – but when they went out of business Stuart took over the site. It made canned, evaporated milk for human consumption that was sold in grocery stores in the Pacific Northwest.
In 1910 Elbridge Amos Stuart bought 350 acres of timber and brush near Tolt. He cleared the land, diked the Snoqualmie River to control its flooding, and bought a purebred bull and 84 registered Holstein cows as the basis for a research dairy herd.
That was Cheese John who came up with the idea of sterilizing the milk by subjecting it to high temperatures, thereby creating the first commercially-produced evaporated milk. The Carnation made evaporated milk until October 1, 1954, when a switch was made to producing the Carnation Instant Milk that had been invented earlier in the year.
In 1985 the Carnation brand was purchased by Nestlé.
